Where is call barring on a Samsung Galaxy?

Phone app → ⋮ (More options, top right) → Settings → Supplementary services → Call barring. On some devices and Android versions the parent item is labelled "Call settings" instead of "Supplementary services."

What is the default call barring password on a Samsung Galaxy?

It's set by your carrier, not by Samsung. Published defaults include 1919 (Vodafone UK) and 0000 (Vodafone Australia, Vi in India). Samsung's own general suggestion, where you don't know it, is to try 0000. Most carriers don't publish a default; ask your carrier rather than guessing repeatedly.

How do I turn off (remove) call barring on a Galaxy?

Open the same Call barring screen, tap the category that's on, and enter the password again. We could not confirm a single "turn off everything" option in current One UI; the documented way to clear more than one category is to switch each one off in turn, entering the password each time.

Why does call barring say "rejected" on my Samsung?

"Call barring rejected" and "Failed to read data" are messages reported by Galaxy owners on Samsung's community forums, not wording Samsung documents officially. Samsung's own troubleshooting lists the likely causes: your carrier doesn't support call barring services, the wrong SIM is selected, the password is wrong, or a network connectivity issue is preventing the settings from applying.

Why does my Samsung say "Failed to read data"?

Same causes as above. It's a commonly reported message, not one Samsung has published exact documentation for, so treat the reported wording as a symptom and work through the carrier, SIM, password and signal checks in section 7 of this guide.

What is the keypad code for call barring on a Samsung?

The same GSM codes as any phone: *33*password# turns on barring of all outgoing calls, #33*password# turns it off, *#33# checks the status. Samsung does not use different codes. Full list: Call Barring Codes.

How does call barring work on a dual-SIM Galaxy?

Separately for each SIM. Pick that SIM's own Call barring item inside Supplementary services; the password is the one for that SIM's line.

Does call barring work on a Galaxy with Verizon, T-Mobile, or AT&T?

Probably not as a self-service code or menu item: we found no *33*-style barring code published by any of the three for mobile lines. Each offers an account-level alternative instead — Verizon Family, T-Mobile Family Allowances, or AT&T's landline-only international block.

Call Barring on Samsung Galaxy: Settings, Password, and "Failed to Read Data" (2026)

NoDial Editorial ／ 2026-10-27

On a Samsung Galaxy, call barring lives in the Phone app, under ⋮ → Settings → Supplementary services → Call barring. Samsung uses its own Phone app and its own menu names, so the path and the screens are not the same as on a Pixel or another Android phone. This guide is about the setting itself: the exact path, what each switch does, the password (defaults, how to change it, what happens if you get it wrong), how a dual-SIM Galaxy handles it, why the switch is sometimes missing, and why it sometimes refuses with "rejected" or "Failed to read data."

If you came here for the general idea of call barring — what it is, the full list of codes, how the network handles it — start with What Is Call Barring? Meaning, Settings, Codes and Password on Android. If you want every way to stop outgoing calls on a Galaxy, including Fixed dialling numbers and a per-number blocker, that is How to Block Outgoing Calls on a Samsung Galaxy. This article stays on call barring itself.

NoDial: Block Outgoing CallsBlocks calls to numbers you choose

NoCall: Blacklist Call BlockerBlock unwanted calls before they ring.

Current as of October 2026, based on carrier device guides for Samsung Galaxy models from S23 through S26 and the A series (Vodafone UK, Vodafone Australia, Three UK, EE, Telstra, Samsung's own support pages), plus Android's public carrier-configuration code. Menu wording varies by One UI version and carrier, and whether call barring is offered at all is decided by your carrier, not Samsung.

1. The short answer

Call barring is a carrier network service, defined in the GSM standard, that refuses whole categories of calls — all outgoing calls, international calls, all incoming calls, and so on. A Galaxy does not do the blocking itself: the Phone app sends your request to your carrier, and the carrier's network applies it. On Samsung's own menu structure, the setting sits inside a group called Supplementary services, alongside call forwarding and Fixed dialling numbers, not under the "Block numbers" screen most people find first.

KEY POINT

Galaxy path: Phone → ⋮ → Settings → Supplementary services → Call barring. It needs a password from your carrier, not from Samsung, and on a dual-SIM phone it is set separately for each SIM. If the item is missing, or the password is refused with "rejected" or "Failed to read data," the cause is usually your carrier, the SIM, the password, or the network, not a fault in the phone itself.

2. Where call barring is on a Galaxy

Current carrier device guides for Android 13 through Android 16 (One UI 5.1 through One UI 8; Galaxy S23 through S26, and the A series) all describe the same path:

Open the Phone app.
Tap the three dots ⋮ (More options) in the top right.
Tap Settings.
Tap Supplementary services. Samsung's own support page notes that the exact label may vary by device and Android version, so on some phones this item is called Call settings instead.
Tap Call barring.

On the current Galaxy S26 screen, Supplementary services lists, in order: Show your caller ID, Call forwarding, Call barring, Call waiting, and Fixed dialling numbers. All of them are carrier-side services, which is why an item such as Call barring can be missing if your carrier doesn't offer it — section 7 covers that.

On a dual-SIM Galaxy, Supplementary services shows a Call barring item for each SIM; tap the one for the SIM you want. Section 6 has more.

QUICK CHECK

No Supplementary services or Call barring item at all? Jump to section 7. Item is there but the password keeps failing? Section 5. Dual-SIM and not sure which line you're changing? Section 6.

3. What each option on the screen does

Opening Call barring shows a set of switches under a Voice calls heading. The names below are the current labels shown on a Galaxy S26 in a carrier's device guide; your model and carrier may word one or two of them slightly differently, but the categories and the codes behind them are the same GSM standard used on every phone.

Group	Option	What it blocks	Code
Outgoing calls	All outgoing calls	Every call you make, except emergency numbers	33
	International calls	Calls to numbers in other countries	331
	International calls except home	International calls, but not to your home country. Useful while roaming, so you can still call home	332
Incoming calls	All incoming calls	Every call to your number	35
Incoming calls	All Incoming calls when roaming	Incoming calls, but only while you are abroad	351

On some older models, and on Samsung's own India support page, there is an extra step where you tap Voice call before the list appears. Current carrier device guides for the S23 through S26 range open straight to the switch list above, under "Voice calls." If your screen asks you to choose, pick Voice call for ordinary phone calls.

The same categories can be dialed directly as codes: *33*password# turns on barring of all outgoing calls, #33*password# turns it off, and *#33# checks whether it's on. These are standard GSM codes, identical on every phone, not something Samsung changes. The full list, including the two international codes and how the codes are built, is in Call Barring Codes: Full List, Password, and How to Reset It.

4. Turning call barring on and off

To turn a category on:

Open Call barring (section 2). On a dual-SIM phone, make sure you're on the right SIM (section 6).
Tap the option you want, for example All outgoing calls.
Enter the call barring password when asked, and confirm.

To turn it off: tap the same option again and enter the password again.

Current carrier guides for the S24 and S24 Ultra describe a ⋮ menu on the Call barring screen itself with a Change barring password option (older models show it as Change password instead — see section 5). We could not confirm a single "cancel all" or "deactivate everything" entry in that menu on current Galaxy devices; the documented way to turn off more than one category at once is to switch off each one in turn, entering the password each time. On standard Android, carriers can also choose whether a "deactivate all" or password-change option appears in this menu; we could not confirm whether Samsung's Phone app follows the same settings.

5. The call barring password

The call barring password is a 4-digit code held by your carrier's network, not by Samsung. It is not your screen lock, your SIM PIN, or your Samsung account password, and there is no password that works on every network. A few carriers publish a default:

Carrier	Published default
Vodafone UK	1919
Vodafone Australia	0000
Vi (India)	0000 (Vi says "usually 0000")

Samsung's own regional support pages (for the Gulf region) suggest trying 0000 as a general starting point if you don't know your password, but this is Samsung's general suggestion, not a password Samsung itself sets. Most carriers do not publish a default at all. If none of the above works, ask your carrier rather than guessing further.

STOP AFTER TWO TRIES

Under the GSM standard, after more than three wrong entries in a row the network stops accepting any password-related request until your carrier resets it. If your first two guesses fail, stop and call your carrier instead of trying a third.

To change the password, use Change barring password (on the S24 and later, per carrier guides) or Change password (older One UI) from the ⋮ menu on the Call barring screen — it asks for the old password, then the new one twice — or dial **03*330*old*new*new# and press call. If your carrier rejects the change, your old password stays in force.

6. Dual SIM: which SIM you are changing

On a dual-SIM Galaxy, call barring and its password are set separately for each SIM. Device guides describe this as picking Call barring on the SIM you want within Supplementary services, rather than a single combined switch for the phone. Samsung's own support page says the same: on a dual-SIM device, select the correct SIM (SIM1 or SIM2) before configuring call barring. Because barring is a service on each SIM's own line, the setting and the password belong to that SIM's carrier account.

If a switch won't turn on or the password is refused, check which SIM's Call barring screen you actually opened before you suspect the password itself.

7. Why it's missing, "rejected," or "Failed to read data"

The Supplementary services or Call barring item isn't there at all

Whether call barring is offered at all is up to your carrier. Samsung's own support page says some carriers may not offer the feature, and on standard Android (for example on a Pixel) the Call barring entry stays hidden unless the carrier's configuration switches it on. So a missing entry on your Galaxy most likely means your carrier doesn't offer it on your line, not that something is broken.

"Rejected" and "Failed to read data"

Galaxy owners have reported these messages on Samsung's community forums: "Failed to read data. Call barring rejected" when trying to switch off a barring option, and, on the same Supplementary services menu (while checking call forwarding), "Failed to read data, check your SIM card or network connection and try again." A plain "call barring rejected" is also reported. These sentences come from user reports on Samsung's community forums, not from a Samsung support page that documents the wording, so treat them as commonly seen messages rather than an official error list.

Samsung's own regional support pages do list the reasons call barring can fail to turn on, without tying a reason to specific wording, and these match what the community reports describe:

Cause Samsung lists	What to check
Your carrier doesn't support call barring services	Ask your carrier whether the service is available on your line
Wrong SIM selected	On a dual-SIM phone, confirm you opened the SIM you meant to change (section 6)
Wrong password	Try a published default once (section 5), then stop and ask your carrier
Network connectivity issues preventing the settings from applying	Check signal strength and try again with a stronger connection

On that last point: on some networks, call settings like barring are exchanged with the carrier over a data connection (the IMS standard handles them that way), so a weak or unavailable connection can make the request fail. On a Pixel this can show up as an explicit "turn on mobile data" message, covered in Call Barring on Google Pixel, section 6; Samsung's device guides don't describe an equivalent message. If none of the four causes above explains it, the full breakdown of Android's call-settings error messages is in Call Barring Not Working: What Each Error Message Means and How to Fix It.

8. Verizon, T-Mobile, AT&T: why a US Galaxy may not have it

If your Galaxy is on one of the three big US carriers, a missing Call barring entry usually isn't a bug to chase. We could not find a self-service *33*-style call barring code published by Verizon, T-Mobile or AT&T for ordinary mobile lines; T-Mobile's own list of self-service short codes, for example, covers call forwarding and call waiting but has no barring code on it.

What each carrier offers instead is managed through your account, not the Phone app's Supplementary services menu:

Verizon offers Call & Message Block for specific numbers, and Verizon Family can "permanently block calls, texts and other messages for up to 20 numbers" on a managed line.
T-Mobile offers Family Allowances, with Always Allowed and Never Allowed number lists for a managed line.
AT&T publishes a "Block Outgoing International Calls" setting, but it belongs to AT&T's Digital Phone / U-verse Voice home landline service, not to a mobile line.

So on a US Galaxy, Supplementary services → Call barring being absent is consistent with how these carriers run their networks, not a sign that your phone or SIM is faulty. The full picture, including what each carrier confirms and doesn't, is in Can You Block Outgoing Calls on Verizon, T-Mobile, or AT&T?

9. Other ways to stop outgoing calls on this Galaxy

Call barring is one of several tools on a Galaxy, and not always the right one for what you're trying to do. In brief:

Block numbers, under Phone → ⋮ → Settings, blocks calls coming in from the numbers on your list. Samsung's manual describes it only for incoming calls; it is not a way to stop yourself calling a number.
Fixed dialling numbers, in the same Supplementary services menu as Call barring, is the opposite logic: an allow-list on the SIM, protected by a separate PIN2.
Samsung Kids, under "My Phone," can limit a child's Galaxy to approved contacts.

Each of these, with exact steps and what they can and can't do, is covered in How to Block Outgoing Calls on a Samsung Galaxy: Barring, FDN, and One Number.

NoDial: block calls to the numbers you choose

None of the built-in tools can stop calls to one particular number while leaving the rest of the phone alone. NoDial does that: you add the numbers you want to stop calling, and each one is blocked always, on set days and times, or after a set number of calls. It runs on the phone, so it works whatever your carrier supports and needs no barring password. Emergency numbers cannot be added.

11. Summary

SUMMARY

On a Samsung Galaxy, call barring is under Phone → ⋮ → Settings → Supplementary services → Call barring, set and password-protected separately for each SIM. The password comes from your carrier, not Samsung, and repeated wrong guesses can lock it. A missing item, or messages like "rejected" and "Failed to read data," are usually the carrier, the SIM, the password, or the network, not a phone fault.

Path: Phone → ⋮ → Settings → Supplementary services → Call barring.
Password: from your carrier (published defaults: 1919 Vodafone UK, 0000 Vodafone Australia and Vi). Stop guessing after two wrong tries.
Changing it: ⋮ → Change barring password, or **03*330*old*new*new#.
Dual SIM: barring and the password are per SIM.
Missing, rejected, or "Failed to read data": usually carrier support, wrong SIM, wrong password, or network — see section 7.
